I use a Yasaka Gatien Extra 3D, and, against the competition I face (granted it's not usually 1500+), inverted chopping with Cream on Japanese sponge or DHS PF4-1 works just fine. I used the Destroyer LPs on a Matsushita blade (BH) for a couple of months but was underwhelmed with the LP side. But let me re-emphasize that I do not think LPs come into their own until you find yourself facing competition that can hit several speedloops in a row.
